Hi Guys,
I played with both green and dried grapefruit leaves. I tracked the
results by using mite trays beneath screened bottom boards.
Extensively smoked hives would drop lots of varroa. But I found that
powder sugar dusting was more consistent and much easier on the lungs.
I found grapefruit leave smoke very obnoxious. It was as bad or worse
than tobacco smoke on this beekeeper. And I would have abandoned it for
that reason, even if it worked perfectly.
Regards
Dennis
